The City of Kelowna has issued a water quality advisory for customers of its utility.
Crews will be checking the status throughout the weekend, in hopes of eliminating the advisory next week.
Water Quality Supervisor Ed Hoppe says that's in large part to the unusually high water levels in Okanagan Lake.
"We're definitely seeing some increased sediment flow and debris heading into the lake through these tributatries, so that's generally resulting in elevated turbidity levels from the sediment that's coming into the lake," he said.
However, the advisory only marks the first stage in the process, as the water quality isn't bad enough for any kind of mandatory action.
This initial step is a warning that kids under 12, seniors over 65, and anyone else with a weak immune system would benefit by boiling tap water for a minute before use.
Hoppe says staff will stay on top of it constantly, but can't say for sure when the advisory will be able to be rescinded.
"At this point we don't know when that might happen, but we're going to be monitoring it through the weekend, to make sure we can get to that point as soon as possible," he said.
"I don't recall the last time this has happened, so this is a little bit unprecedented."
As of a couple weeks ago, the city said it had been more than 20 years since its utility had seen a water quality advisory come down.
The utility is also asking customers to limit water use for only essential tasks, so that crews can flush the line more frequently.
